T all whore it may concern Be it known that I, HENRY S. Ration,

A a citizen of the United States, residing at Jackson, in the county ot'Jackson and State of Michigan, have invented certain new anduseful'lrnprovements in Starting Devices for Explosive-Engines, of whichthe following is a specification.

This invention relates to starting devices for explosive-engines, and ithas :tor one ol its objects' the provision of a mechanism which ishand-operable and adapted to rotate the engine shaft several times forcach straight-line movement of the operating lever.

The invention has, furthermore, for its object the provision of novelmeans for automatically connecting' and .disconnecting the handoperatcdshaft ot' the device with and from the engine-shaft, :ll as will hereinafter appear and be partieularl)7 defined in the claims.

The invention has been clearly illustrated in the accompanying drawings,iu which similar characters denote similar parts, and in which'- Figurel is a top view of my in'iproved device, Fig. Q is an end View thereof,Fig.

.8 shows xa central longitudinal section of the same, Fig. ft is a viewcorrespmiding to Fig". 1, and illustrates an interinediate position oilsome ot' the parts during t'heiroperation, Fig. Vi is a section on line5, of Figi'. l, on an enlarged scale, and Fig. 6 represents theelement'` shown in Fig. 5 in another position.

Brieflyl stated the present device is intended to replace the crankeommonly used when starting' an explosive engine oF the compressiontype. especially `in automobiles, power boats, and the like, so that ahand lever may he used with a single stroke in one direction to turn theengine-shaft over a. number ot times and thus start the engineunder itsown power, whcreup m the hand lever may be allowed to return and toauto-b matically disengage. the operalinn memher ol the device vtrom theengine sha t't.

Rdferrine; to the drawings, 10 denotes a base plate provided with ways'll for slidably supporting a reriprm-atorv slide 12. Thisslidl-i hashearings 13, lt in which is journaled a shal't l5 which eonstitutes thedriving: rnemher loi; the engine shaft. lli to which it may be coupledhv a clutch menthol' 17 cooperative with a similar member 18 on theengine shaft 16. The driver 15 earrles a bevel pinion 19 fast thereon ineonstant engagement with a sector 20 journalcd on a stud'Ql seeurel)7held in the slide l. An extension 22 on the sector may be emploved toconnect the latter by a rod 2S with the hand-lever (not shown), fornetnating the device. A torsional springlr Q-t surrounds the shaft. 15and has one end at tached to the pinion 19, as at Qt', whileits otherend 2li rests against the upper face of the slide. the organizationheine such that said spring will return the shaft and sector rotativetvto the position shown in l* 1g. 1, 1n which the device is shown normal,

and the retrograde movcmentof the sertorl limited b v a stop'pin 2strikingr against a holding-plate QG whereby proper mesh is n'mintainedbetween the sector and pinion, as will be readiliy understood.

.From the foregoing' it will he seen that.,V

a pull exerted on tho rod 23 in the. direction ot arrow n., Fig. 1, theshaft. 15 will he rotated, and, in order to bring the clutch members 1Rinto engagement. so that the rotation ol the sha'l't 15 may ho utilitedto operate the engine-shaft siumltauoously, the entire slide 1Q togetherwith all the parts carried thereby, is positively moved toward the leftin Fig. l, the result heiner aecomplished by a roller 27 rotatable on astud' Q8 held in the hase 10, (see also Fig. 5), and engaging a 'cam 99on the sector during its lmtlal rotative movement. This means,

that the slidel 1Q will he moved bodily, with the sector, pinion. shaft,and clutch memher 17 until the latter has tullv engaged the clutchmember 18, (see Fig. 4l whereupon the engine shaft lwill be carriedalongr rotatively, and the torsional spring 24 placed under additionaltension. lVhen now the engine starts under its own power, and natu rallyat a greatly accelerated speed, the cam faces of the clutch-members willmerely push the slide hack; the. same thing will also occur when thepull on the rod 23 is released` in which case a spring 30 will tend topull .the slide and all its parts hack to normal position, e.\'eeptinf,l that the roller Q7 may come to rest against the inner 'face 31 ot'the seetor-rim- Means are. therefore, provided for permittingr the iullreturn movement, rotatively, of the sector wit-hout necessarily movimgYthe slide forward again'.

Tn thc present instance l aeeomplisln thi-S- result by cutting theunderside 2V of the be depressed during the 'return movementA of thesector, as indicated by arrow7 Ae iti may happen that the forward.

movement of the slide l2 may bring the ad jacent faces of the clutchmembers into abutting relation, it may be desirable to render theengine-shaft member i8 slightly yieldable, as for inst-ance by a spring33 interposed between said member and a Collar 34 fixed on the shaft i6.

Many Qhanges may be made in the particular eonetruetien and organizationof Some of the component elements of my improved device Withoutdeparting; from the spirit of the invention.
